---

malignant hyperthermia  an autosomal dominant inherited condition affecting patients undergoing general anesthesia, marked by sudden, rapid rise in body temperature, associated with signs of increased muscle metabolism, and, usually, muscle rigidity.

hy·per·ther·mi·a (hpr-thûrm-)

n.

Abnormally high body temperature, usually resulting from infection, medication, or head injury, and sometimes brought about intentionally to treat diseases, especially certain cancers.

hyperthermia

[hī′pərthur′mē·ə]

Etymology: Gk, hyper + therme, heat

1 a much higher than normal body temperature induced therapeutically or iatrogenically.

2 

Usage notes: nontechnical.

malignant hyperthermia.

3 the use of various heating methods, such as electromagnetic therapy, to produce temperature elevations of a few degrees in cells and tissues. It is believed to lead to an antitumor effect. Hyperthermia may be used in conjunction with radiotherapy or chemotherapy for cancer treatment.

hyperthermia (hī´purthur´mē),

n an extremely high fever brought on by treatment.

hyperthermia, malignant

n an extremely high fever accompanied by muscle rigidity that occurs rapidly in susceptible individuals when they are exposed to certain types of anesthesia; may be fatal.

hyperthermia

1. greatly increased body temperature. May have effect as teratogen.

2. heat therapy. Used in the treatment of tumors, often in conjunction with chemotherapy or radiation. Whole body, regional or localized hyperthermia is induced with electromagnetic radiation, radiofrequency current heating or ultrasonic heating.

epidemic hyperthermia

poisoning by Neotyphodium (Acremonium)coenophialum.

idiopathic hyperthermia

term applied in error to the effects of ergotism under conditions of high ambient temperature. See also rye ergot, Neotyphodium(Acremonium) coenophialum.

malignant hyperthermia

a drug induced stress syndrome of pigs which have been treated with halothane or suxamethonium. Isolated cases have been reported in dogs and cats. The clinical syndrome includes muscle rigidity and hyperthermia. It is fatal and susceptibility to it is inherited. See also porcine stress syndrome.

hyperthermia

Hyperpyrexia Mainstream medicine A condition defined as a corporal temperature of ≥ 42ºC; the body defends itself with peripheral vasodilation–↓ effective volume, resulting in ↑ pulse rate–a response to perceived blood loss, ↓ cardiac efficiency, hypoxia, ↑ permeability of cell membranes with ↑ potassium, followed by cardiac failure. See Malignant hyperthermia Oncology A type of treatment in which tissue is exposed to high temperatures to damage and kill CA cells, or ↑ CA cell sensitivity to RT and chemotherapy.
